PUMP.

SPECIFICATION forming part of Letters Patent No. 393,311, dated November 20,1888.

Application filed April l2, 1887.

To @ZZ whom, it may concern:

Beit known that I, PHILIP A. MYERS, of Ashland, in the county of Ashland and State of Ohio, have invented a new and useful Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to pumps. The form shown is what is known as a drill-well pump.77 Some of the parts, however, are adapted to any form of pump.

The invention includes an improved stand for the pump, and a cylinder head or cap connecting the cylinder with the pipe by which it is supported, and includes also an improvement in the parts for holding the valve-seat in place.

The invention is illustrated in the accompanying drawings, in which- Figure l shows the' pump partly in section and partly in side elevation. Fig. 2 shows a similar View of the pump-stand ona larger scale. Fig. 3 shows a central longitudinal section of the cylinder and cylinder-head andthe valvein central longitudinal section on a larger scale. Fig. 4 is a similar section of the pumpcap shown in Fig. 3, the sectionbeing taken at'right angles to that shown in Fig. 3. Fig. Fig. 6 is a side elevation of the pump-cap. Fig. 7 isa section on line y y of Fig. 6. Fig. 8 is a side elevation of the valve-seat.

In the drawings, A represents the pumpstand, which is cast preferably in one piece, though, if desired, it may be made in sections of any desired ornamental surface or figure. The lower part from the point a to the bottom of the stand is cast hollow, and the bottom of the stand is provided with a iiange, b, by means of which it is fastened in place. With the upper part is cast or attached the standard B, upon which the pump-handle C is pivoted. The hollow interior of the pump-stand forms an air-chamber for the pump. The pipe D, through which the water is forced up into the pumpstand, is screwed into the bottom d of the pump-stand, and the water discharges directly into this chamber at the bottom.

The nozzle E of the pump has an extension Serial No. 234,549. (No modem which terminates near the bottom of the chamber in the pump-stand, and the upper part of the chamber being closed air-tight, as hereinafter explained, the whole upper part ofthe hollow pump-stand becomes an air-pressure chamber to cause a steady flow of the water from the spout. The bottom d is formed concave upon its upper surface, so that no water will stand therein, but will all drain off through the pipe D. The nozzle is attached to the pump-stand by means of a union, F. The nozzle is screwed into the upper part of this union, the lower part of the union being screwed into an opening in the top of the stand. The lower part of the union has an interior thread, into which the pipe eis screwed. This forms a secure .u

connection for all the parts, and allows the nozzle to be turned to the right or left, as may be desired.

On the standard is an arm, g, with a vertical hole in it, through which the extensionG of the pump-rod may be passed, and in which it is guided when the pump is designed for connection with a windmill. The hollow stand is made preferably elliptical, or approximately so, in cross-section, as shown in Fig. 5, with the larger axis in line with the handle, and it is at the same time ornamental and vaffords a rm support for the pump without the use of braces.

The guide-pipe H, which connects at its lower end with the submerged cylinder, and through which the pump-rod passes,is screwed air-tight into a hole in the top plate of the hollow stand,so that although the pump-rod passes freely through this the air-chamber is made tight without the use of packing.

The outer pipe, D, or stock-extension and the inner or guide pipe, H, are of such relative diameter as to leave an annular space around the inner pipe, and these pipes are connected,respectively,to the inner and outer or forcing cylinders,in general effect as shown in Letters Patent of the United States granted to me on the 5th day of September, 1882; but the union between the pipes and the cylinders is made by means of a cap of special construction. This cap is shown at K. It is cast all in one piece, and has a lower plate, 7c, Fig. 4,

having a threaded vertical flange, I, to connect with the outer cylinder, L, which is screwed thereon against a packing, Z. The upper part of the cap consists of a hollow arch,

M, in which the passages m open on each side.

below within the flange I, and above into thc cylindrical part N. This part N has an interior thread to receive the stock-extension pipe D,so that there is a passage on each side through the hollow arch upward into the pipe D. The interior guide-pipe, II,is threaded and screwed into a hole, n, in the center of the inner wall of the hollow arch,wl1ere it terminates. The piston-rod passes from the end of` the guidepipe through an open space under the arch, and then through the hole n in the plate K. I drill a hole through the crotch of the inner wall of the arch, which hole opens into the space beneath the same, this serving as a frostvent, and by reason of its construction preventing the washing of the walls of the well, as the water will simply flow down the exterior surface of the cylinder. v

From the center of the plate 7c underneath extends downward a hollow cone, O, the upper part of which opens through the hole n of the plate in line with the bore of the inner pipe. The lower part forms vertical flange o, threaded to connect with the interior or submerged cylinder, P, between which and the outer cylinder, as explained in my said patent, is a space for the passage of the water. There is also an annular space between the flange I and the flange o and cone O, through which the water may pass into the passages in the hollow arch, and thence up through the pipe D. This single casting forms,therefore,acon nection between the upper pipes and the interior and exterior cylinders, strong and conlplete in itself, with all the passages and connections without exceeding in diameter the outer cylinder. This casting, therefore, has seven distinct functions or parts. The lower cone, O, serves as a support for the submerged cylinder l?, and its shape allows an abundance ot' water-space at its upper end. The outer flange, I, of the plate or base holds the outer cylinder. The upper end holds the main pipe or stock-extension D, and the crotch or crown of the arch holds the guide-pipe. The hollow arch forms passages for the water. The open space beneath the arch allows the water which accumulates above the upper bucket to pass off,so that it is not retained in the guide-pipe. The frost-vent allows the discharge ofthe drainage; butone of the mostimportant functions or features of this cap is that as it is constructed I am enabled to thread and machine it so that when screwed to the parts it brings at once the entire pipe into line and avoids friction. In the lower part of this cylinder I have shown my improved valve-seat connection. A union, Q, threaded at 2, fits the lower end of the outer cylinder. The upper part is of slightly-reduced diameter, and is threaded at 3 to fit the valve-ring Ri. This valve-ring is adapted to lit inside of the outer cylinder-and has cars-i, by means of which it may be turned onto the union. The upper edge is formed with an inwardly-extending flange, 5, beneath which is placed the valve-seat It. It is in the form of a ring and made of glass, porcelain, vulcanite, or any suitable non-corrosible material. Next to this is placed a suitable washer-as vulcanized rubber or leather-and the whole is held securely in place by turning the valvering down upon the upper threaded extension of the union. This holds the valve and its seat securely in place, and the whole isunited to the lower end of the cylinder by means of the interior threads of the lower ends of the cylinder engaging with the lower threaded surface. The suction-pipe S is screwed into a polygonal boss, T, on the lower end of the union. By this construction one piece (the union) forms the connection between the cylinder and the suction-pipe, and forms also a part of the means for holding the valve-seat. This construction also leaves the cylinder at this end of the same diameter at other points. Further, the glass or other frangible seat is underlaid by packing in every part, and is securely clamped by merely screwing the parts together and may be removed by the simple unscrewing. The flange also holds the clapper-valve by the same means and without screws.

I am aware that caps or couplings have been heretofore known for connecting the cylinders below with the pipes above-for example, as shown in the patent of Williams, No. 318,066, granted by the United States Iatent Office May 19, 1885-and I do not broadly claim such connection.

I claim as my invention-- 1. In combination with thebarrel-extension, as D, of a pump, with a piston-rod pipe, the outer cylinder, L, and a submerged cylinder, a cap or coupling consisting of a plate, k, having a flange for the outer cylinder, a hollow cone for the submerged cylinder, said cone opening centrally through the plate 7c, the flange and the cone being adapted, respectively, to connect with the outer and the submerged cylinders, a hollow arch on the upper part of the plate c,with openings through said plate to the space below an opening and above into the cylindrical part N, a hole in the inner wall of the crown of the arch in line with the opening in the plate leading to the interior of the hollow of the cone, the construction specied being fitted to the pipes and cylinders, and leaving a space under the arch above the plate 7c for the escape of the water, all substantially as described.

2. A valve-seat connection consisting of a union adjustably connected to the cylinder, a flanged valve ring adjustably connected to said union, and a valve, valve-seat, and suitable packing arranged between the valve-ring and the upper end of the union, substantially as described.
